Abstract Classical sexual selection theory predicts that males should mate eagerly, yet blue monkey males often reject females’ sexual invitations. We evaluated how males’ responses to female solicitations related to female characteristics, number of males and conceptive females present, and the male’s recent copulations. Using 12 years of data from a wild population, we found that males accepted only 20% of female solicitations. Odds of acceptance (copulation) increased for conceptive females, for females with whom the male copulated recently, and when fewer males were present. Odds of accepting nulliparous females decreased when more conceptive females were available, consistent with market models. Male responses did not relate to female rank or matings with other females the same day. When males responded negatively, nulliparous females were especially likely to receive aggression vs. mere refusal. Overall, males’ decisions to mate with willing females depended both on female characteristics, especially fertility, and on social context.

Abstract Background: By studying population size, activity patterns, diet, and ranging ecology of Boutourolini’s blue monkey (Cercopithecus mitis boutourlinii) we can get sufficient information to conserve the subspecies in the area. Boutourlini’s blue monkey is endemic subspecies found in the western and northwestern parts of Ethiopia. The study was conducted in Apini and Dokuma forests, northwestern Ethiopia, from October 2018 to June 2019. The block count method was used to estimate its total population size and scan sampling method was used to collect data for activity patterns, and diet. The ranging ecology of the study subspecies was determined for each group based on the point to point movements of the group between consecutive GPS locations recorded. Results: On average a total of 71 and 111 individuals of Boutourolini’s blue monkey were counted in Apini and Dokuma forests, respectively. Boutourolini’s blue monkey spent 47.5% and 48.6% of time feeding, 20.2% and 18.6% moving, and 14.1% and 13.5% resting by the Apini and Dokuma groups, respectively. The Apini group frequently fed on young leaves (52.8%), fruits (30.2%), and mature leaves (6.6%), while the Dokuma group fed on young leaves (39.8%), fruit 942.3%), and mature leaves (8.3%). Ranging ecology of Boutourolini’s blue monkey was 44.4 ha and 78.3 ha for the Apini group, and 51 ha and 56.9 ha for the Dokuma group during the wet and dry seasons, respectively. Conclusions: The total population size of blue monkeys in the Apini and Dikuma forests counted were different. Activity budgets vary during the wet and dry seasons. During the entire study period blue monkeys consumed different food items from the two forests. The home range size of blue monkeys during the two seasons was different in both groups and they traveled long distance during the dry season. As the habitats of Boutourolini’s blue monkey in the present study area is degraded due to various anthropogenic activities, there is a need to design strategies to minimize conservation problems of the subspecies in the area.

The excavation of the ‘House of the Frescoes’, discovered in 1923 by Sir Arthur Evans to the north-west of the Palace at Knossos, revealed a large deposit of fresco fragments from floral and faunal compositions in Room E on the ground floor. From the broken pieces Evans's Swiss draughtsman, E. Gilliéron fils, was able to reconstruct three ‘panels’: these show a blue monkey on a red backgroundin a rocky and floral setting (PM II, pl. x, opp. p. 447; here called ‘panel A’); a blue monkey on an unpainted white ground in a papyrus thicket (ibid. 451, fig. 264, here ‘panel B’); and a blue bird perched on a rocky outcrop surrounded by wild flowers (ibid., pl. xi, opp. p. 454, here ‘panel C’). Evans thought panels A and B in particular contained Nilotic elements, and he suggested that the monkeys might have been depicted as hunting for birds' eggs, possibly of waterfowl. In addition, Evans published designs for the restoration of pancratium lily, myrtle and ‘jet d'eau’ compositions, and illustrations of fragments showing the head of a third monkey and part of a second ‘jet d'eau’.The ‘House of the Frescoes’ was constructed after the earthquake at the end of M.M. IIIB and was destroyed in L.M. IA, as shown by pottery of that period on the floors of the house. The paintings therefore belonged to a single period of occupation, and evidently formed in some way a unified system of decoration ‘in the same style, by the same hands and executed at the same time’.
